Close-up detail of the Interchange. The portal-braced bridge tower can be seen clearly here. The track of the Airport Railway is not visible in this photo as it runs in the lower deck section of Tsing Ma Bridge and, when arriving at the bank on Tsing Yi Island, heads underground.

The main cable outside the cable chamber. The hexagonal object seen on the upper side of the cable is the hydraulic cable compacting clamp, the object on the lower side is the cable sorter. The 33,000 separate 5.38 mm galvanised steel wires are sub-divided into 80 strand groups before being tied onto the cable anchor.

Cable strands being tied onto the gravity anchor through adjustable tying bolts. The bolts are anchored to the gravity anchor which is made of mass concrete and weighs some 150,000 tonnes.

The cast iron cable stay which holds the two pairs of hanging cables for the bridge deck in position. The steel ribbon tapes, located at 1.5 m intervals, are temporary ties for the compacted steel wires that form the main cable.

The final sealing of the main cable. A strong epoxy resin-based paint is used to seal the surface of the cable which is then wrapped with a skin of galvanised iron wire. The rectangular-shaped device is the equipment used to carry out the wire wrapping.
